You use cards for offline authentication (bars/festivals/etc.), and use a different process for online authentication.
Proving someone has the physical card in their possession (which is what a reader does) isn't really useful for proving identity when you can't also check the picture.
Mmm. Good point. Otherwise, somebody could just steal the card from you and insert it into the reader and would therefore be you. My guess is something like that would at least require some sort of OTP 2 factor authentication. If you were going to do it that way, and it would have to be application based and definitely not text based.
